    Step-by-step explanation:

    selling \: price \: of \: 12 \: articles = 80Rs

    profit = 33\frac{1}{3}%

    profit%=\frac{profit}{Cost \: Price} × 100

    \frac{100}{3} =\frac{S.P. - C.P}{C.P} × 100

    \frac{1}{3} =\frac{80 - C.P.}{C.P.}

    \frac{1}{3} =\frac{80}{C.P.} - 1

    \frac{80}{C.P.} =\frac{4}{3}

    \frac{20}{C.P.} =\frac{1}{3}

    Cost \: price = 20 × 3 = 60Rs.

     Cost \: Price \: of \: 12 \: articles = 60Rs.

    Cost \: price \: of \: one \: article = 5Rs.

    5 rupees = 1 \: article

    then ,90 \: rupees =\frac{90}{5}=18 \: articles
